USC Mech II (111 species mechanism) was<br>applied as a master mechanism. First, 1D simulation was conducted by applying so-called plug flow<br>reactor model and 34, 23, 20, 18, and 19 species mechanisms were suggested as candidates of reduced<br>mechanisms. In addition, 0D ignition delay simulation by applying so-called perfectly stirred reactor<br>model by CHEMKIN-Pro, 2D reacting flow simulation by CRUNCH CFD, and 3D reacting flow simulation<br>by RANS were performed to choose the most suitable reduced model. As a result, the 20 species (96<br>reactions) mechanism which consists of H2, O2, N2, H2O, CO2, CO, H, O, OH, HO2, CH2, CH2*, CH3,<br>HCO, CH2O, CH3O, C2H2, C2H3, C2H4, and CH2CHO was selected as the best reduced reaction<br>mechanism for C2H4 fueled 3D simulation.<\/p>\n\n\n\n<p><a href=\"https:\/\/aerospacerepository.org\/wp-content\/uploads\/2023\/10\/HiSST-2022-187.pdf\" data-type=\"link\" data-id=\"https:\/\/aerospacerepository.org\/wp-content\/uploads\/2023\/10\/HiSST-2022-187.pdf\">Read the full paper > <\/a><\/p>\n","protected":false},"excerpt":{"rendered":"<p><b>Kan Kobayashi, Sadatake Tomioka, Masahiro Takahashi, and Masatoshi Kodera<\/b><\/p>\n<p>DOI Number XXX-YYY-ZZZ<\/p>\n<p>Conference Number HiSST-2022-187<\/p>\n","protected":false},"author":1,"featured_media":0,"comment_status":"open","ping_status":"open","sticky":false,"template":"","format":"standard","meta":{"footnotes":""},"categories":[993,1009,1006],"tags":[1127,966,933,1128,1126],"class_list":["post-16175","post","type-post","status-publish","format-standard","hentry","category-events","category-high-speed-missions-and-vehicles-hisst-2022","category-hisst-2022","tag-combustion-simulation","tag-flight-test","tag-propulsion","tag-reaction-mechanism","tag-scramjet-engine","category-993","category-1009","category-1006","description-off"],"_links":{"self":[{"href":"https:\/\/aerospacerepository.org\/index.php\/wp-json\/wp\/v2\/posts\/16175","targetHints":{"allow":["GET"]}}],"collection":[{"href":"https:\/\/aerospacerepository.org\/index.php\/wp-json\/wp\/v2\/posts"}],"about":[{"href":"https:\/\/aerospacerepository.org\/index.php\/wp-json\/wp\/v2\/types\/post"}],"author":[{"embeddable":true,"href":"https:\/\/aerospacerepository.org\/index.php\/wp-json\/wp\/v2\/users\/1"}],"replies":[{"embeddable":true,"href":"https:\/\/aerospacerepository.org\/index.php\/wp-json\/wp\/v2\/comments?post=16175"}],"version-history":[{"count":1,"href":"https:\/\/aerospacerepository.org\/index.php\/wp-json\/wp\/v2\/posts\/16175\/revisions"}],"predecessor-version":[{"id":16176,"href":"https:\/\/aerospacerepository.org\/index.php\/wp-json\/wp\/v2\/posts\/16175\/revisions\/16176"}],"wp:attachment":[{"href":"https:\/\/aerospacerepository.org\/index.php\/wp-json\/wp\/v2\/media?parent=16175"}],"wp:term":[{"taxonomy":"category","embeddable":true,"href":"https:\/\/aerospacerepository.org\/index.php\/wp-json\/wp\/v2\/categories?post=16175"},{"taxonomy":"post_tag","embeddable":true,"href":"https:\/\/aerospacerepository.org\/index.php\/wp-json\/wp\/v2\/tags?post=16175"}],"curies":[{"name":"wp","href":"https:\/\/api.w.org\/{rel}","templated":true}]}}
